some more pictures ,
2nd picture shows the british cans , various manufacturers , such as BMB , VM , PSC , W&W, all fabricated before 1945,
the "early style" cans are different at the cap , the rivet to hold the flexible lid , is at the yellow can hollow , as it is on all my other "late" cans
on the green can , the used rivet has a solid top , cap is also slightly different from the other one , any ideas someone ?
the yellow can still has a (fading) red ink stamp , MT 80 , at which the 80 stands for octane number , but what stands "MT" for ?
